Ingredients
Scale
Ingredients
- 1 whole garlic head, unpeeled, cut in half horizontally
- 1 onion, peeled and quartered
- 2 rosemary sprigs
- 4.5 lb leg of lamb, bone-in (or shoulder)
- Salt and pepper, to taste
- 1.5 tbsp olive oil
- 3 cups beef broth
- 2 cups water
Instructions
- Prepare the Oven and Aromatics: Preheat the oven to 335°F (170°C). In a large roasting pan, arrange the halved garlic head, quartered onion, and rosemary sprigs evenly to create a fragrant bed for the lamb.
- Season the Lamb: Place the leg of lamb on top of the garlic, onion, and rosemary. Generously season the entire surface of the lamb with salt and pepper, rubbing it in thoroughly to enhance flavor. Drizzle the olive oil evenly over the lamb to help it brown and keep it moist.
- Add Liquids: Pour the beef broth and water around the lamb, ensuring not to wash away the seasoning. The liquid will help create steam and keep the lamb tender during slow roasting.
- Cover and Roast: Cover the roasting pan tightly with aluminum foil (prefer foil over a lid to allow minimal steam to escape). Place the pan in the preheated oven and roast the lamb slowly for about 4 to 4.5 hours. Cooking time may vary slightly depending on the size of the lamb leg.
- Remove Foil and Turn the Lamb: After the initial roasting period, carefully remove the roasting pan from the oven and peel back the foil. Turn the lamb over so it can brown evenly on all sides.
- Continue Roasting Uncovered: Return the roasting pan to the oven uncovered and roast the lamb for an additional 45 minutes. This allows the surface to develop a nice crust and the meat to fully tenderize.
- Rest and Serve: Remove the lamb from the oven and use a spoon to baste the roast with the pan juices to keep it moist. Let the lamb rest briefly before carving and serving to ensure juices redistribute evenly.
Notes
- Do not leave the lamb uncovered during the initial roasting to prevent the meat from drying out.
- Alternative fresh herbs like sage or thyme can be used in place of rosemary for different flavor profiles.
- If leg of lamb is unavailable, lamb shoulder is a suitable substitute with similar results.
- To store leftovers, keep the lamb with some cooking liquid in an airtight glass container in the refrigerator for up to 3 days.
- For reheating, warm the lamb in the microwave or oven along with the cooking juices to maintain moisture.
- To freeze, remove meat from the bone and place it in a freezer-safe bag. Frozen lamb can be kept for up to 2 months.
